Electronic duo Phantogram has dabbled in the realm of hip hop through their collaborations with Big Boi -- first on his album Vicious Lies & Dangerous Rumors, then on their joint EP Big Grams. A-Trak, of course, is no stranger to the hip hop world himself... Danny Brown's "Smokin' & Drinkin'" is still one of the most monumental bangers of the last five years.

Phantogram and A-Trak unite on an upbeat new track called "Parallel Lines," debuted today on Zane Lowe's Beats 1 show. During an interview with Lowe, A-Trak explains that he constructed the song using a demo with instrumentals played by Phantogram.
